AcuVu Inline Hygrometer - ACCESSORIES
by Shaw Moisture Meters

These dew point transmitters from Shaw connect into the AcuVu:

Shaw - AcuDew Dew Point Transmitter
2 wire, 4-20 mA loop powered transmitter.  Various dewpoint ranges are available covering an overall range from -120 °C to +20 °C (-184 °F to +68 °F) dewpoint and output units are configurable in °C dewpoint, °F dewpoint, ppm(v), ppb(v), g/m³ and lb/MMSCF.

    Starting at:
    Shaw - SDT-Ex Dew Point Transmitter
    Compact, 3 wire, 4 – 20 mA , the Model SDT-Ex is certified intrinsically safe to ATEX: Ex II 1 GD Ex ia IIC T4 Ga (-20 °C ≤ Ta ≤ +60 °C) and IECEx: Ex ia IIIC T200135 °C Da (-20 °C ≤ Ta ≤ +60 °C) for use in hazardous areas using a signal isolator.

     Sample systems that work in tandem with the dew point transmitters:

    Shaw - SU4 Sample System
    Designed to reduce the dryer/process line pressure, provides pressure and flow suitable for measurement. The inlet and outlet fittings are stainless steel, choose connection size (⅛ NPT, ¼ NPT or 6 mm).

      Starting at:
      Shaw - Dew Point Sensor Holder
      Manufactured from solid stainless steel and houses the dewpoint sensor in inline installations.

       Signal Isolator when using SDT-Ex

      Shaw - Signal Isolator

      Zener Barrier Unit (signal isolator), shunt diode safety barrier, is used for inline applications in potentially hazardous areas or where there is a high risk of fire or explosion and comes in a custom enclosure.  Available in two versions:

      • ATEX: Ex II 1 GD Ex ia IIC T4 Ga (-20 °C ≤ Ta ≤ +60 °C)
      • IECEx: Ex ia IIIC T200135 °C Da (-20 °C ≤ Ta ≤ +60 °C)
